Add "kvm@vger.kernel.org" to this thread. Here is the more additional information. I suspect that this is a problem related to virtualization. I ran the following program simulates raid6_avx21_gen_syndrome() in kernel both on the host and on the guest. ``` #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <err.h> #define PAGESIZE 4096 #define DISKS 4 typedef unsigned char u8; typedef unsigned long u64; static const struct raid6_avx2_constants { u64 x1d[4]; } raid6_avx2_constants __attribute__((aligned(32))) = { { 0x1d1d1d1d1d1d1d1dULL, 0x1d1d1d1d1d1d1d1dULL, 0x1d1d1d1d1d1d1d1dULL, 0x1d1d1d1d1d1d1d1dULL,}, }; static void raid6_avx21_gen_syndrome(int disks, size_t bytes, void **ptrs) { u8 **dptr = (u8 **)ptrs; u8 *p, *q; int d, z, z0; z0 = disks - 3; /* Highest data disk */ p = dptr[z0+1]; /* XOR parity */ q = dptr[z0+2]; /* RS syndrome */ asm volatile("vmovdqa %0,%%ymm0" : : "m" (raid6_avx2_constants.x1d[0])); asm volatile("vpxor %ymm3,%ymm3,%ymm3"); /* Zero temp */ for (d = 0; d < bytes; d += 32) { asm volatile("prefetchnta %0" : : "m" (dptr[z0][d])); asm volatile("vmovdqa %0,%%ymm2" : : "m" (dptr[z0][d]));/* P[0] */ asm volatile("prefetchnta %0" : : "m" (dptr[z0-1][d])); asm volatile("vmovdqa %ymm2,%ymm4");/* Q[0] */ asm volatile("vmovdqa %0,%%ymm6" : : "m" (dptr[z0-1][d])); for (z = z0-2; z >= 0; z--) { asm volatile("prefetchnta %0" : : "m" (dptr[z][d])); asm volatile("vpcmpgtb %ymm4,%ymm3,%ymm5"); asm volatile("vpaddb %ymm4,%ymm4,%ymm4"); asm volatile("vpand %ymm0,%ymm5,%ymm5"); asm volatile("vpxor %ymm5,%ymm4,%ymm4"); asm volatile("vpxor %ymm6,%ymm2,%ymm2"); asm volatile("vpxor %ymm6,%ymm4,%ymm4"); asm volatile("vmovdqa %0,%%ymm6" : : "m" (dptr[z][d])); } asm volatile("vpcmpgtb %ymm4,%ymm3,%ymm5"); asm volatile("vpaddb %ymm4,%ymm4,%ymm4"); asm volatile("vpand %ymm0,%ymm5,%ymm5"); asm volatile("vpxor %ymm5,%ymm4,%ymm4"); asm volatile("vpxor %ymm6,%ymm2,%ymm2"); asm volatile("vpxor %ymm6,%ymm4,%ymm4"); asm volatile("vmovntdq %%ymm2,%0" : "=m" (p[d])); asm volatile("vpxor %ymm2,%ymm2,%ymm2"); asm volatile("vmovntdq %%ymm4,%0" : "=m" (q[d])); asm volatile("vpxor %ymm4,%ymm4,%ymm4"); } asm volatile("sfence" : : : "memory"); } static char *data[DISKS]; int main(void) { int i; for (i = 0; i < DISKS; i++) if ((errno = posix_memalign((void **)&data[i], PAGESIZE, PAGESIZE))) { err(EXIT_FAILURE, "posix_memalign() failed"); } raid6_avx21_gen_syndrome(DISKS, PAGESIZE, (void **)data); exit(EXIT_SUCCESS); } ``` ``` $ cc -O2 -o test test.c ``` It succeeded on the host and failed with "Illegal Instruction" on the guest. There is avx2 flag on /proc/cpuinfo of both the host and the guest.

The OSXSAVE CPUID bit is not set by QEMU, it is set by the OS itself (indirectly) when it sets CR4.OSXSAVE. QEMU says it's not available (probably) because the Opteron_G3 CPU model does not have the 0xD CPUID leaf. I think you're using libvirt's "host-model" CPU model. That model needs QEMU/libvirt support for each host CPU family, and in general it often gives rise to bugs such as the one you're reporting, Change it to host-passthrough, and please send us the output of /proc/cpuinfo so we can add support for Ryzen in "host-model".

It looks like the cause is that AMD has removed TBM instructions compared to e.g. Piledriver, so libvirt resorts to a much older base model (thanks to Dave Gilbert for sorting through the list of feature bits).
